Attribute Based Multifactor Authentication for Cloud Applications

Online information maintenance through cloud applications allows users to store, manage, control and share their information with other users as well as cloud service providers. There have been serious privacy concerns about outsourcing user information to cloud servers. But also due to an increasing number of cloud data security incidents happened in recent years.

Proposed system provides privacy to users data with efficient authentication and store them on cloud servers such that servers do not have access to sensitive user information.
